redux-socket.io/dist/index.js：找不到预设\\“ es2015 \\”

Question

I installed "redux-socket.io" and when I run the app again it shows and error like this:

error: bundling failed: "TransformError: ../../../../node_modules/redux-socket.io/dist/index.js: Couldn't find preset \\"es2015\\"

How to solve this?

Answer 1

If you're using babel, you have to install babel-preset-es2015 and use it in your .babelrc , eg:

{
  "presets": ["es2015"]
}

Hope that this can help :)
